阅读下列短文，从每题所给的四个选项（A、B、C、D）中选出最佳选项。 A report consistently brought back by visitors to the US is how friendly，courteous and helpful most Americans were to them．To be fair，this observation is also frequently made of Canada and Canadians，and should best be considered North American．There are，of course，exceptions．Small-minded officials，rude waiters，and ill-mannered taxi drivers are hardly unknown in the US．Yet it is an observation made so frequently that it deserves comment．For a long period of time and in many parts of the country, a traveler was a welcome break in an otherwise dull existence． Dullness and loneliness were common problems of the families who generally lived distant from one another．Strangers and travelers were welcome sources of diversion，and brought news of the outside world．The harsh realities of the frontier also shaped this tradition of hospitality． Someone traveling alone，if hungry，injured，or ill，often had nowhere to turn except to the nearest cabin or settlement．It was not a matter of choice for the traveler or merely a charitable impulse on the part of the settlers．It reflected the harshness of daily life： if you didn‘t take in the stranger and take care of him，there was no one else who would．And someday，remember，you might be in the same situation．Today there are many charitable organizations which specialize in helping the weary traveler．Yet，the old tradition of hospitality to strangers is still very strong in the US，especially in the smaller cities and towns away from the busy tourist trails．“I was just traveling through，got talking with this American，and pretty soon he invited me home for dinner—amazing．” Such observations reported by visitors to the US are not uncommon，but are not always understood properly． |
